Specification of Letters Patent. -Pa,tented Mar 31 1914,

Original application filed April 12, 1919, Serial No. 554,932. Divided and this application filed July 5 1912. Serial No. 707,691.

.To all whom it may concern Be it known that I, Junrus H. HAMPP, citizen of the United States, residing in the city of New York, borough of Bronx, county and State 'of New York, have invented a certain new and useful Material-Clamping Mechanism for Slicing-Machines, of which the following'is a specification.

This invention '18 a material clamping mechanism for slicing machines, the same being in part a division of a prior application filed by me April 12, 1910, Serial No. 554,932.

The objects of the'invention are to securely retain the material in a fixed position upon a table regardless of the shape of the mass of such material; to easily and quickly release the retaining means, and to release the locking means and adjust the retaining means by the movement of a single operating device.

The invention embodies a carrying member and a material clamping member pivoted to said carrying member whereby said clamping member is adapted to adjust or accommodate itself to the shape of the material, whereas the carrying member is movable in a direction to shlft the clamping member according to the size of the mass of material.

The invention embodies means cooperating with a rack for locking the carrying bar, and a single operating device so related to the carrying bar and to the locking means that by a certain movementof said operating device the locking means is released and movement is imparted to the carrying bar.

In a preferred form, the lockin means is a dog pivoted to the carrying ar and held by a spring normally in engagement with the rack bar. The operating member is a piece pivoted to the carrying bar, said member having a stud ositioned for engagement with the locking dog and provided, also, with a toe piece adapted for engagement with the carrying bar. As

stated, the dog is normally in fixed engagebar; then the toe piece bears upon the carryin bar, or a part thereof, so as to have a firm earing thereon, and thereafter the carrying bar with the pivoted clamp is. shifted up or down accordlng to the direction of movement of the operating piece, during Wl'llCh movement the dog is held in a repressed position and free from engagement with the rack bar.

Other features of the invention, and the advantages thereof, will appear from the annexed detailed descriptiofi.

In the accompanying drawings, I have illustrated one practical embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, 2nd not as defining the limits of the inven- Figure 1 is a side elevation'of my material clamping mechanism applied to a part of a slicing machine. Fig. 2 is a plan view thereof. Fig. 3 is an elevation of a art of the device with the locking member 1n a released position. Fig. 4 is a transverse section taken on the line 4-4 of Fig. 1. Fig. 5 is a like section taken on the line 55 of Fig. 1, and Figs. 6 and 7 are detailed perspective views of the operating member and the locking member, respectively.-

A, designates a table, shown in the accompanying drawings as a part of a material slicing machine, said table being provided with a post B positioned on one side thereof so as to extend upwardly. The upper end of this post is bifurcated, as at b, and within said bifurcated portion is pivoted one end of a carryin member or bar C by means of a pin 0. t the other side of table A, is an upright rack, D, the same being provided on one of its edges with a series of ratchet teeth d. Said rack is curved on an arc, the center of which is co incident with the pin 0.

E, designates an operating member, shown in detail in Fig. 6 of the drawings, said member being embodied as a lever having one of its ends forked at e. The forked end of said lever is provided with depending ears'e', e, whereby said lever is constructed in a manner for the forked end thereof to straddle the rack bar D, and be pivotally attached to the bar C by meansof'the pin 0 which passes through said bar and through said depending ears e of said lever.

The locking member for bar C is shown as a dog F, the same Consisting of a yoke f and an arm f. The yoke f straddles the forked end of the lever, andthe ears 6' of the operating member are positioned be tween the yoke and the sides of carrying bar C, said ends of the yoke having apertures f through whichpasses the pin 0 see Fig. 4, whereby the dog is pivoted to the carrying bar C by the same pin which serves as the pivot for the operating member E. The free end of the arm f is slotted so as to .straddle a post G, the latter extending upwardly from the bar C, and a spring 9 is coiled around said post between the bar or carrying member C and the arm f of the lock-mg member, which spring normally exerts tension upon the locking dog andpresses the forward edge f of said dog into engagement with a tooth of the rack D, thus securely locking the carrying bar C'against upward movement.

1The operating member E is provided with a stud e, which is so positioned (see dotted lines in Figs. 1 and 3) as to be in operative relation tothe yoke f of the dog F when said dog is in a normal locked position. Said operating member E is provided, also, with a toe piece, 6, which toe piece lies between two studs or stops 0 positioned on the carrying bar, said, studs or stops limiting the'up and down movement, respectively, of the. toe. piece.

On the carrying bar C, intermediate the ends thereof, is a depending hanger lug 0 the latter having near its end an aperture 0 see Fig. 5. To this hanger lug is loosely con- 1 nested a, material clamping member H,'the

latter being provided with a forked arm H. fiaid forked .arm straddles the de ending hanger lug c and is secured thereto y a pin it, passing through the aperture 0 in the lug and similar apertures in the forked arm H.

The gripping member H is provided,

preferably, with a roughened under surface, suchvv as the impaling teeth in, shown in Fig. 1., and av similarseries of spikes a, may be provided on the table A, the same being adapted to co'o perate with the teeth h for holding the material to be sliced in fixed position.

The operation of the device is as foliowsz-Withthe carrying bar in a raised position, the looking member engages with a tooth near the upper end of the rack. The material .te be sliced can now be easily ineerted beneath the .clamping member H and impaled upon thespikes upon the table A. It is only necessary to press downwardly upon member E, bring toe piece 6 into con tact with stud a and this downward pres sure impelsbar so and clamp in? in the same V direction, the sliding freely over the i of the reel;

shifted downwardly until the roughened When the carrying bar menses on the carrying bar to force the teeth into said material. This operation of gripping j/the material is facilitated by having the member H pivoted to the carrying arm, for the reason that said member readily adapts itself to the shape of the material. When the said material has been gripped sufficiently tight to adequately hold it in fixed position while the slicing operation is going on, the pressure on the handle e is relaxed, and the spring 9 lifts the arm 7" and moves the dog into engagement with the rack, thereby locking bar C and clamp H in fixed positions. lVhen it is desired to remove the material, the operator raises the lever E, as This indicated by the arrow in Fig. 1. movement brings the stud 6 into engagement with the forward edge of dog F, and

presses said dog rearwardly against the ten-' sion of the spring 9, whereby the dog is disengaged from the tooth of the rack bar. Now, when the dog has been forced back to secure sufficient clearance between the nose of the dog and the teeth of the rack, the toe piece e on the operating member engages the stop 0, see Fig. 3, thereby securing a firm bearing of the operating member upon the carrying bar, whereby pressure upon the operating member results in shifting the carrying bar in an upward direction.

It will be noted that the dog and operat ing member cooperate so effectually that but a slight movement of the latter is required to speedily disengage the said dog from the rack, the dog moving in almost a straight path when pressure is applied to disengage the dog.

When the slicing operation is completed,

.the operating lever E may be pressed upwardly, thus releasing the dog from the rack and allowing the carrying bar to be raised to a position where it will not interfere with present invention as particularly well adapted for-use as a material clamping mechanism for sllclng machines, it is evident that the device may be used, either in whole or in part, in other arts.

As heretofore stated, the invention of this application is a division of my prior application. Serial No. 554,932, except as to memher 0 and the bifurcated structure of the dog.

Having thus fully described the invention, what E claim as new, and desire to secure by Letters Patent is v 1.
